plz solve these puzzles nd giv proper solutions.


1) 11,8,17,14,23,24,31,32

2)4,2,5,9,5,11,13,7,16,17,9

3)0,8,12,26,23,43

4)7.2,2.2,3.2,16,11,12,60,55,56

5)18,24,5,21,18,27,17,23,4,24,30

6)2,3,10,15,26,35,50

• 1)notice the prime no series of the above series. 11,13,17,19,23,29,31,37,41
  plz leave the middle prime no.
  don't think about the8,14,24,32..it's quite tricky qus abt prime no.
  so the actual series will be 11,8,17,14,23,24,31,32,41
  so the answer is 41.

• (1*1) + 1 = 2
  (2*2) – 1 = 3
  (3*3) + 1 = 10
  (4*4) - 1= 15
  (5*5) + 1 = 26
  (6*6)– 1 = 35
  (7*7)+ 1 = 50
  (8*8) - 1 = 63
  so the answer is 63

• 3)12-0 = 12
  23-12 = 11
  33-23 = 10
  So The Answer will be 33
  also notice this
  26-8= 18
  43-26= 17
  59-43=16.

• 2)(4,2,5),(9,5,11),(13,7,16),(17,9,?)
  13-9 =4
  7-5 =2
  16-11 =5
  similarly,17-13=4
  9-7=2
  21-16=5 , ans=21

• 4) multiply 3rd term with 5(of every group consisting consecutive 3 no.s)
  so ans is- 56*5=280
  6)add 13(9+4) to 50.
  every 2nd term is increased by 1 and follwed by 4. ans=63.

• 5.first of all the series will be 18,24,5,21,27,8,17,23,4,24,30,?
  The solution is...
  18+6=24,24-19=5
  21+6=27,27-19=8
  17+6=23,23-19=4
  24+6=30,30-19=11
  so 11 is the next term.

• 2) (4,2,5),(9,5,11),(13,7,16),(17,9,?)
  
  4-2=2 | 4+1=5
  9-4=5 | 9+2=11
  13-6=7 |13+3=16
  17-8=9 |17+4=?=21

• 2) (4,2,5)(9,5,11)(13,7,16)(17,9,?)
  Now consider every 1st term:4+5=9,9+4=13,13+4=17
  2nd term:2+3=5,5+2=7,7+2=9
  3rd term:5+6=11,11+5=16,16+5=21
  hence the ans is: 21

  4) (a,b,c); (a, a-5, b+1);a=c*5......56*5=280
  2) (abc)(4-2=2,9-4=5, 13-6=7, 17-8=9 )
  (2+3=5, 5+6=11, 7+9=16, 9+12=21)........21

• 6) group the terms like : (2,3,10),(15,26,35),(50,..,..).
  now see the diff of 2 n 3.i.e->1; 10 n 15 i.e-> 5; 26 n 25-> 9
  now the diff of 1,5 is 4 n similarly 5 n 9.
  so u need to add 4 with 9. i.e 13 and then add it with 50 to get the ans.(63)

• (7.2,2.2,3.2),(16,11,12),(60,55,56)
  each group has 5 as difference btw 1st two term and 1 as addition like(7.2-2.2=5 , 2.2+1=3.2)...last term of each grp is multiple of 5times of adjacent group like(3.2*5=16).....we get 56*5=280..as a next term

• answer to question 1 will be 39.
  2x5 +1=11
  2x4=8
  2x8+1=17
  2x7=14
  2x11+1=12
  2x12=24
  2x15+1=31
  2x16=32
  2x19+1=39
  since (two consecutive numbers repeated between a gap of 3,3.4,4) like 8-5=3,11-8=3, 15-4=11, 19-4=15)so the last num to b multiplied is 19

• 3) divide series as 0, 12, 23, ? and 8, 26, 43....Now 8+18=26, 26+17=43 similarly 0+12=12 , 12+11=23, 23+10=33 ...Answer is 33

• 6)2=1^2+1
  3=2^2-1
  10=3^2+1
  15=4^2-1
  26=5^2+1
  35=6^2-1
  50=7^2+1
  x= 8^2-1
  x=63

• 2) we take (4,2,5)=5-2=1..leave 2
  (9,5,11)=11-9=2..leave 5
  (13,7,16)=16-13=3...leave 7
  so the next group should be (17,9,21)=4.. leave 9.
  so answer will be 21.

• 4) 7.2 , 2.2 , 3.2 , 16 , 11 , 12 , 60 , 55 , 56
  7.2 - 5 =2.2
  2.2 + 1 =3.2
  3.2 * 5 =16
  16 - 5 =11
  11 + 1 =12
  12 * 5 =60
  60 - 5 =55
  55 +1 =56
  56 * 5=280
  ans is 280

• 3) Take alternating series and a no. to get next no.and then decrease by 1
  (0,0+12,12+11)=(0,12,23)
  (8,8+18,18+17)=(8,26,43)
  so here next one comes like 23+10=33

• 0,8,12,26,23,43 there is mistake
  
  0, 8, 12, 26, 32 , 43...is okkkk and sol. is
  diff b/w 0 and 8 is 1,2,3,4,5,6,7 are 7 numbers means 7/2=3.5=3 after round
  diff b/w 8 and 12 is 3...
  
  diff b/w 12 and 26 is 13,14,15,16,17,18,19, 20, 21, 22, 23, 24, 25 are 7 numbers means 13/2=6.5=6 after round

• Clearly notice the series 11,8,17,14,23,24,31,32
  the above series looks like 11,13,17,19,23,29,31,37,41 prime number series
  now the actual sol is 11,(13-5),17,(19-5),23,(29-5),31,(37-5),41
  Hence the answer is 41 hope you understand the logic here
